Popco Av Scarlett Thomas

<p>Alice Butler has been receiving some odd messages - all anonymous, all written in code. Are they from someone at PopCo, the profit-hungry corporation she works for? Or from Alice''s long lost father? Or has someone else been on her trail? <br><br>The solution, she is sure, will involve the code-breaking skills she learned from her grandparents and the key she''s been wearing round her neck since she was ten. <br><br><i>PopCo</i> is a grown-up adventure of family secrets, puzzles, big business and the power of numbers.</p>
